Mycobacterium smegmatis

A series of structome analyses, that is, quantitative and three-dimensional structural analysis of a whole cell at the electron microscopic level, have already been achieved individually in Exophiala dermatitidis, Saccharomyces cerevisiae, mycobacterium smegmatis, Mycobacterium tuberculosisMyojin spiral bacteria, and Escherichia coli.

Mycobacterium smegmatis is an acid-fast bacterial species in the phylum Actinomycetota and the genus Mycobacterium. It is 3. It was first reported in November by Lustgarten, who found a bacillus with the staining appearance of tubercle bacilli in syphilitic chancres. Subsequent to this, Alvarez and Tavel found organisms similar to that described by Lustgarten also in normal genital secretions smegma. This organism was later named M. Some species of the genus Mycobacterium have recently been renamed to Mycolicibacterium , so that M.

Mycobacterium smegmatis

The genus Mycobacterium contains several slow-growing human pathogens, including Mycobacterium tuberculosis, Mycobacterium leprae, and Mycobacterium avium. Mycobacterium smegmatis is a nonpathogenic and fast growing species within this genus. In , a mutant of M. Classical bacterial models, such as Escherichia coli, were inadequate for mycobacteria research because they have low genetic conservation, different physiology, and lack the novel envelope structure that distinguishes the Mycobacterium genus. By contrast, M. Dissection and characterization of conserved genes, structures, and processes in genetically tractable M. Notably, tuberculosis TB drugs, including the first-line drugs isoniazid and ethambutol, are active against M. Furthermore, Bedaquiline, the first new TB drug in 40 years, was discovered through an M. With a repertoire of bioinformatic and physical resources, including the recently established Mycobacterial Systems Resource, M.
